    DVB-H Introduction Modulation System DVB-H 2 Introduction The R&S Signal Generator enables you to generate signals in accordance with the DVB-H (Digital Video Broadcasting - Transmission System for Handheld Terminals) standard. To playback a signal from a waveform file created by the simulation software R&S WinIQSIM2, the corresponding R&S WinIQSIM2 digital standard option must be installed.

  • Page 10: Outer Coder

    DVB-H Introduction Modulation System DVB-H The data packets of the input stream are transformed to a Pseudo Random Binary Sequence (PRBS) in order to obtain a bit sequence that has a positive effect on the transmitted RF spectrum. The PRBS polynomial is specified as: 1 + x The PRBS generator is loaded with the sequence "100101010000000"...

    DVB-H Introduction Modulation System DVB-H The integrated puncturer removes bits from the redundant data stream. Puncturing slightly impairs the characteristics of the code. The code rates that can be set are 1/2, 2/3, 3/4, 5/6 and 7/8. The code rate can be selected according to the required trans- mission characteristics of the system.

    DVB-H Introduction Modulation System DVB-H Modulation Mode Sub-Stream v QPSK 16-QAM 64-QAM In hierachical mode, the high priority stream is demultiplexed into two sub-streams and the low priority stream is demultiplexed into v-2 sub-streams. The outputs of the v bit interleavers are grouped to form the digital data symbols, such that each symbol of v bits will consist of exactly one bit from each of the v interleavers.

  • Page 13: Frame Adaption

    DVB-H Introduction Modulation System DVB-H 2.1.7 Frame Adaption The transmitted signal is organized in super-frames. Each super-frame consists of 4 frames. Each frame contains scattered pilot cells, continual pilot carriers, and TPS carriers. The pilots can be used for frame synchronization, frequency synchronization, time synchro- nization, channel estimation, and transmission mode identification.

    DVB-H Introduction Extensions to DVB-T 2.1.8 Transport Parameter Signalling The Transport Parameter Signalling (TPS) carriers are used to signalling parameters related to the transmission scheme. The TPS is transmitted parallel on 17 TPS carriers for the 2K mode, 34 carriers for the 4K mode, and 68 carriers for the 8K mode. Every TPS carrier in the same symbol conveys the same differentially encoded information bit.

    DVB-H Introduction Extensions to DVB-T Fig. 2-4: In-Depth Interleaver for 2K and 4K Mode 2.2.2 Time-Slicing The time-slicing module provided with DVB-H reduces the average power consumption of the receiving handheld terminals and enables smooth and seamless service hand- over. IP datagramms are transmitted as data bursts in small time slots using a significantly higher instantaneous bit rate compared to traditional streaming bit rates.
